The NPO/ NAO and Interdecadal Climate Variation in China

This article discusses the interannual variation of the North Atlantic Oscillation (NAO) and North Pacific Oscillation (NPO), its relationship with the interdecadal climate variation in China which is associated with tile climate jump in the Northern Hemisphere in the 1960's. using the data analyses. It is clearly shown that both the amplitudes of the NAO and NPO increase obviously in the 1960's and the main Period of the oscillations changes from 3-4 years before the 1960's to 8-15 years after the 1960's. Therefore. interdecadal climate variation in China or the climate jump in the 1960's is closely related to the anomalies of the NAO and NPO.
